Berfungsi sebagai cerobong pembuangan gas hasil pembakaran batu bara menuju atmosfir. 2. ID Fan A&B (Induced Draft Fan) Fan yang berfungsi untuk mempertahankan pressure pada furnace boiler supaya bernilai negatif dengan cara mengalirkan gas
4.6 Both SAHs are working when SAH A trips & SAH B continues to run: The gas inlet damper, the secondary air outlet damper of the tripped AH shall be automatically closed. The gas outlet damper, the secondary air inlet damper of the tripped AH need not be closed.
AH-2 – air heater second degree SAH – separate air heater D n – nominal load of the boiler (steam production), t/h D – range of thermal load of the boiler, % t w – surface temperature on the pipe wall in the gas part, C ∗Corresponding Author. E-mail address
(SAH) is mounted on the air inlet of the AH, which main-tains the exhaust gas temperature at the AH outlet above the acid dew point. In addition, by using ceramic for the low-temperature elements, we reduced the corrosion of the elements and ash clogging. 3.1
1/2/2011 · The air preheater, for example, though it has few moving parts, is vital to maintaining efficient boiler performance. In this second installment of our Power 101 series, we examine performance
10 stages steam–air heaters (SAH) are set in series with the corresponding regenerative heater. The air is heated by extraction steam to the hot air temperature in multi-stage SAH. Download : Download high-res image (751KB) Download : Download full-size .

7/3/2011 · Dry gas losses High excess air and lower heat absorption in the boiler system can cause exit gas temperature higher than expected resulting dry gas loss. A 22 deg C rise in exit temperature can rise the heat rate one percent. 6. 7.
integrated with steam-air heater (BPF-SAH)" thermal system is carried out by taking a 1 000 MW single reheat ultra-supercritical coal- ﬁ red power plant as a case unit. Although these two
SAH OUTLET AIR TEMP: 120 2. BOILER의 구조 다음 도면은 KAWASAKI BOILER의 전형적인 구조를 나타낸다. FURNACE는 SCREEN WATER TUBE에 의해 전방위가 둘러싸여 있어 열효율을 높이고 방열벽에 높은 열이 가해지지 않도록 되어
15/6/1994 · The boiler produces 4,500,000 lb/hr of steam for a General Electric steam turbine generator rated at 688 MWe. Figure 2-1 is a diagram of the process. Combustion air is supplied from two sources, the primary and secondary air systems. Ambient air is drawn into
The boiler bank is arranged between two drums and hence the name bi- drum boilers. 5 f Learning modules material- Engineering (FB) Single drum boiler: With increase in operating pressures, the drum plate thickness increases considerably and the bi-drum …
The hot air produced by SAH can be used as a source of heat for process heating in industrial applications, crop drying in agriculture, preheating of air in boiler furnaces, etc. Thermal
11/12/2015 · OXYGEN AT BOILER OUTLET To Ensure complete combustion of the fuel used, combustion chambers are supplied with excess air. Excess air increase the amount of oxygen and the probability of combustion of all fuels. EA= (O2% /21- O2% )x100 Stoichiometric Combustion fuel + Oxygen in the air are in perfect balance-. CO2% or O2% in flue gas is an
SAH is the heat supplied by the steam air heater. At steady-state, Eqs. (1) and (2) become (5) d dt of boiler inlet water and outlet steam. The steam flow rate becomes the output. Since the number of the output is one, the number of the neuron of the output
Moreover, a three-stage PAH and a double-stage SAH are arranged to accomplish the air preheating for the WtE boiler. Partial feedwater obtained from the RH6 outlet is taken to the PAH1 and SAH1 to warm the air; afterward, the feedwater extracted from the

conventional heat exchangers such as GAH and SAH) in order to improve the running costs. (2) An oxygen analyzer was added at the outlet of the boiler in order to improve the controllability of the incinerator during low excess air ratio combustion. (3) The
outlet of the two Secondary Air Heaters (SAH) upstream of the precipitators. It was decided at the time not to condition the flue gas flow exiting the Primary Air Heater (PAH), which represents approximately 20% of the flue gas flow. At the time, there was
